caruncle |
= strophiole |
STRUCTURE |
|
An outgrowth from the seed coat (testa) around or near the hilum and micropyle, or from the raphe. |
caryophyllaceous |
= diacytic |
architecture |
stomate |
Having two subsidiary cells that together surround it, their common wall oriented perpendicular to its long axis. |
caryopsis pl. caryopsides |
= grain (not recommended); < achene |
nominative |
fruit |
The achene of a grass [Poaceae (Gramineae)]. Although in traditional use caryopsis (or grain) has been treated as a type separate from achene, they do not differ in basic morphology. |
casing |
|
STRUCTURE |
|
The portion (if any) of a floral tube that is adnate to the gynoecium. See also collar, neck. |
catadromous |
|
venation |
|
Having the first lateral vein in each pinna or primary segment of the frond arise from its midvein on the side toward the base of the frond, the pinnule or secondary segment that it leads to often disproportionately larger than the next distal ones. |
catkin |
= ament |
nominative |
inflorescence |
Elongate, more or less flexible and spike-like, often unisexual, the central axis bearing numerous diminutive flowers inserted either singly or in cymules, the pedicels or secondary axes subtended by small, paleaceous bracts or scales, the whole often deciduous as a unit. |
catkinate |
= amentate |
architecture |
inflorescence |
Comprising one or more catkins. |
caudate 1 |
= tailed |
apex |
laminar structure |
Terminating in a relatively long, flexible, narrowly acuminate tip composed of laminar tissue. |
caudate 2 |
= tailed |
base |
|
With one or more relatively slender, retrorse basal enations or appendages. |
caudex pl. caudices |
|
STRUCTURE |
|
The short, persistent, thickened, more or less erect, main stem of a perennial plant that otherwise has annual stems. |
caudicle |
= translator arm |
STRUCTURE |
|
An attenuate end portion by which a pollinium adheres to a pollinating insect, either directly or by means of a terminal viscidium, the latter, when present, sometimes attached by an intervening stipe; esp. in Asclepiadaceae, Orchidaceae. |
caulescent |
= stemmed |
architecture |
plant |
Having at maturity an evident, elongate, aboveground stem or stems from which branches, leaves, and/or reproductive axes arise at one or more levels along its length. |
cauline |
|
insertion |
|
Upon, arising from, or otherwise directly associated with the stem. |
cauline |
|
position |
|
Upon, arising from, or otherwise directly associated with the stem. |
cell 1 |
|
STRUCTURE |
|
Any of the basic structural/functional units that collectively or individually make up the various tissues of a plant; comprising, at least while physiologically active, a nucleus with included genetic material (chromosomes), a surrounding cytoplasm with included organelles (e.g., ribosomes, mitochondria, plastids), an enclosing membrane, and an exterior cellulosic wall. |
cell 2 (not recommended) |
= chamber (not recommended), locule |
FEATURE |
|
Any structurally distinct compartment within an anther, ovary, fruit, sporangium or other organ; not necessarily having any evolutionary integrity. |
central |
= medial, median |
insertion |
|
At, upon, or closely ranged about the structural or symmetrical midpoint or axis. |
central |
= medial, median |
position |
|
At, upon, or closely ranged about the structural or symmetrical midpoint or axis. |
centralium pl. centralia |
|
FEATURE |
|
A central longitudinal cavity within the seed; esp. in Arecaceae (Palmae). |
centrifugal |
|
development |
|
Proceeding away from the center, thus more advanced centrally than peripherally within a given frame of reference. |
centripetal |
|
development |
|
Proceeding toward the center, thus more advanced peripherally than centrally within a given frame of reference. |
ceraceous 1 |
= cereous, waxen, waxy; > caesious, glaucescent, glaucous, pruinose |
coating |
|
Covered with wax or a wax-like substance. |
ceraceous 2 |
cereous, waxen, waxy |
texture |
|
Having the consistency of wax. |
cereous 1 |
= ceraceous, waxen, waxy; > caesious, glaucescent, glaucous, pruinose |
coating |
|
Covered with wax or a wax-like substance. |
cereous 2 |
= ceraceous, waxen, waxy |
texture |
|
Having the consistency of wax. |
